Title: Dimensional stabilisation of cellulosic textile materials
IPC: D06M13/123
Filed: 1948-01-02
Abstract: Cellulosic artificial silk materials, e.g. fabrics formed from viscose rayon, acetate rayon or cuprammonium rayon, are chemically modified by impregnating them with a solution or dispersion of pyruvic aldehyde in the presence of an organic acid and thereafter heating the impregnated material, e.g. from 120 DEG  to 100 DEG  C. for 5 minutes.  The impregnated material may be stretched to its original dimensions and may be maintained so stretched during the heating operation.  In an example, a viscose rayon fabric is impregnated with a solution of 12.3 parts by weight of pyruvic aldehyde and 1.5 parts by weight of oxalic acid in 288 parts by weight of water, stretched to its original dimensions and dried. The fabric is then heated at 140 DEG  C. for 5 minutes and bleached with aqueous sodium hypochlorite solution.ALSO:Cellulosic textile materials, e.g. fabric formed from cotton, viscose rayon, acetate rayon, or cuprammonium rayon in the form of mono-or multi-filament or staple fibre yarns, are dimensionally stabilized to laundering by impregnating them with a solution or dispersion of pyruvic aldehyde in the presence of an organic acid and thereafter heating the impregnated material, e.g. from about 120 DEG  C. to about 160 DEG C. for about 5 minutes.  The impregnated material may be stretched to its original dimensions and may be maintained so stretched during the heating operation.  In an example a viscose rayon fabric is impregnated with a solution of 12.3 parts by weight of pyruvic aldehyde and 1.5 parts by weight of oxalic acid in 288 parts by weight of water, stretched on a tenter to its original dimensions and dried.  The fabric is then removed from the tenter, heated at 140 DEG C. for 5 minutes and bleached with 0.5 Tw. aqueous sodium hypochlorite solution.  The process is said to be especially applicable to regenerated cellulosic materials.  The pyruvic aldehyde may be applied as a solution or dispersion in an organic liquid and the organic acid used may be acetic or tartaric.

Title: Hydrogenation of steroids
IPC: C07J75/00
Filed: 1953-01-02
Abstract: A D 4-double bond in a steroid nucleus is saturated (producing predominantly a normal configuration of hydrogen in the 5-position) by the action of hydrogen in the presence of a catalyst consisting of palladium supported on a carbonate or oxide (or mixture thereof) of a metal of group 2B of the Periodic Table. The starting materials may contain substituents such as keto, hydroxy, acyloxy, carboxy or carbalkoxy groups, e.g. in the 3, 7, 11, 12, 17, 20 and 21 positions. The reaction may be effected at 0-100 DEG  C. (advantageously at room temperature), and at atmospheric or raised pressure (e.g. up to 100 lb./square inch), if desired in the presence of a solvent (preferably an alcohol), and is preferably continued until approximately one molar equivalent of hydrogen has been absorbed.  The products may be purified by chromatography.  Examples describe the hydrogenation of (1)-(3) 11a -hydroxyprogesterone to 11a -hydroxypregnane-3 : 20-dione (in methanol in the presence of palladium supported on (1) zinc carborate-zinc oxide mixture, (2) zinc oxide and (3) cadmium carbonate); (4) desoxycorticosterone acetate to 21-acetoxypregnane - 3 : 20 - dione (as in (2)); (5) cholestenone to coprostanone (in methanol in the presence of palladium on cadmium carborate-cadmium oxide mixture); (6) progesterone to pregnane-3 : 20-dione (in methanol in the presence of palladium on zinc carbonate).  Other starting materials specified are D 4-androstene-3 : 17-dione, adrenosterone, corticosterone, 3 : 11-diketo-D 4-etiocholenic acid, testosterone, 17b  - hydroxyprogesterone, 3 - keto - 11b  : 17a -dihydroxy - D 4 - etiocholenic acid, 17a -hydroxycorticosterone, 17 - hydroxydesoxycorticosterone and dehydrocorticosterone. Specification 724,094 is referred to.ALSO:The double bond in D 4 : 5-steroids is saturated by hydrogenation in the presence of a catalyst, the catalyst being palladium supported on a catalyst support comprising a carbonate or oxide of a group 2B element, viz. zinc, cadmium or mercury, or a mixture thereof.  The catalyst may be prepared by adding an excess of a dilute aqueous solution of an alkali metal carbonate to a warm, aqueous solution of a chloride or other water-soluble salt of zinc, cadmium or mercury, to form the precipitated carbonate, which is then slurried in an aqueous solution of a palladium salt, e.g. palladium chloride, aqueous formaldehyde or other lower alkyl aldehyde added, and the resulting mixture warmed to about 60 DEG .  The mixture is made alkaline to pH 9, e.g. with potassium hydroxide, when the palladium-group 2B metal carbonate catalyst precipitates and after washing with water, is dried at about 210 DEG  C.  Prolonged drying may cause decomposition of the carbonate and leave the palladium supported on the corresponding group 2B metal oxide or a mixture of oxide and carbonate.  Details for the preparation of palladium on zinc carbonatezinc oxide and on cadmium carbonate are given.  Specification 724,094, [Group IV (a)], is referred to.

Title: Improvements in or relating to the manufacture of gloves from rubber or flexible thermoplastic materials
Inventor: DAVIS FREDERICK LEWIS
IPC: B29C41/14
Filed: 1955-01-05
Abstract: Gloves made by the dipping process have a better surface internally than externally, and so are customarily turned inside out before sale.  However, the glove so turned does not lie closely on the hand. The present invention uses a dipping former which has the shape of a glove that has been turned inside out. Gloves made on this "inside-out former" are turned inside out to give a true-shaped glove which lies closely on the hand and has the better surface on the outside.  The inside-out former is made by taking a former having the true shape of a hand, making a glove from this "true" former, turning the glove inside out and making the inside-out former from the inside-out glove.  The inside-out former may be made from the inside-out glove (a) by those methods described in Specification 784,702 in which a former is produced in a mould having the shape of an inside-out glove, or (b) filling the inside-out glove with any suitable material to give it a degree of rigidity and copying its shape by means of a copying machine.
